Police computer expert Paul Wells said Lyburd’s laptop was used to access a “Dark Web” marketplace site called Evolution. A user named “Donald Trump” paid for gun parts and ammunition with the online currency Bitcoin.

Lyburd was arrested Nov. 3 after police received a tipoff from someone alarmed by his Facebook posts.

Dry said Lyburd told police he had planned a massacre — but also said the plot was a fantasy he did not plan to carry out.

Lyburd has pleaded guilty to making pipe bombs and explosive devices, and possessing a 9mm Luger Glock gun, bullets and CS gas. He denies possessing the items with intent to endanger life.
